Morris Oxford

Automatic transmission fluid capacity & service interval

Morris Oxford automatic transmission fluid capacity ranges from 2,99 to 6,39 liters. Service intervals include checks at 5000 km and 10000 km. The data covers 2 configurations.

Additional Notes

  • The Morris Oxford automatic transmission carries a total fluid capacity of 6.39 liters, a figure that reflects a full overhaul or dry fill rather than a routine service top-up, since the system holds fluid across both the gearbox and the torque converter circuit.
  • The torque converter alone accounts for 2.99 liters of the total 6.39-liter fill, meaning nearly half the system's fluid volume resides in the converter rather than the main transmission housing.
  • The Series VI Saloon produced from 1961-1966 carried a fluid check interval of 5,000 km under normal use conditions, while the same body style produced from 1966-1971 extended that interval to 10,000 km, also under normal use conditions.
  • Both the 1961-1966 and 1966-1971 Series VI configurations share identical total and torque converter capacities at 6.39 liters and 2.99 liters respectively, indicating no mechanical change to the transmission's fluid volume between those two production periods.
  • A check interval, as opposed to a drain-and-fill interval, means the fluid level is inspected and topped up as needed rather than fully replaced, so the 5,000 km and 10,000 km figures represent inspection frequency rather than full fluid exchange schedules.
